Here you’ll find official materials as well as useful game resources and play aids. A link to a third-party site doesn’t mean that we agree with or endorse all of the opinions on that site.
Chaosium and other companies have very kindly agreed to let us put conversion notes for their excellent adventures up here for ToC users. You’ll need the original CoC adventure, of course! Special thanks to Arseny Kuznetsov for this section.
And the other way around; here, our Trail of Cthulhu adventures have been converted for Chaosium’s classic Call of Cthulhu. You’ll still need the original Trail of Cthulhu adventures to play these!
Be warned – these links will contain game spoilers, so if you haven’t read the campaign or you’re hoping to play it, don’t read these!
